FUEL-FILLER CAP
WARNING
• Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seri-
ously injured if it is misused or mis-
handled. Always stop the engine and
do not smoke or allow open flames or
sparks near the vehicle when
refueling.
• Do not attempt to top off the fuel
tank af ter the fuel pump nozzle
shuts off automatically. Continued
refueling may cause fuel overflow,
resulting in fuel spray and possibly a
fire.
• Use only an original equipment type
fuel-filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious
malfunction and possible injury. It
could also cause the
Malfunc-
tion Indicator Light (MIL) to come on.
• Never pour fuel into the throttle body
to attempt to start your vehicle. •
Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable
fuel containers:
– Always place the container on the
ground when filling.
– Do not use electronic devices
when filling.
– Keep the pump nozzle in contact
with the container while you are
filling it.
– Use only approved portable fuel
containers for flammable liquid.
CAUTION
• Do not use a fuel that contains more
than 15% ethanol in your vehicle. For
additional information, see “Fuel rec-
ommendation” (P. 10-4).

Pre-driving checks and adjustments3-25

•Underneath the bumper and the cor-
ner areas of the bumper cannot be
viewed on the RearView Monitor be-
cause of its monitoring range limita-
tion. The system will not show small
objects below the bumper, and may
not show objects close to the bum-
per or on the ground.
• Objects viewed in the RearView
Monitor differ from actual distance
because a wide-angle lens is used.
• Objects in the RearView Monitor will
appear visually opposite compared
to when viewed in the rearview and
outside mirrors.
• Use the displayed lines as a refer-
ence. The lines are highly affected by
the number of occupants, fuel level,
vehicle position, road conditions and
road grade.
• Make sure that the trunk is securely
closed when backing up.
• Do not put anything on the rearview
camera. The rearview camera is in-
stalled above the license plate. •
When washing the vehicle with high
pressure water, be sure not to spray it
around the camera. Otherwise, water
may enter the camera unit causing
water condensation on the lens, a
malfunction, fire or an electric shock.
• Do not strike the camera. It is a preci-
sion instrument. Otherwise, it may
malfunction or cause damage result-
ing in a fire or an electric shock.
The following are operating limitations and
do not represent a system malfunction:
• When the temperature is extremely high or low, the screen may not clearly display
objects.
• When strong light directly shines on the camera, objects may not be displayed
clearly.
• Vertical lines may be seen in objects on the screen. This is due to strong reflected
light from the bumper.
• The screen may flicker under fluorescent light. • The colors of objects on the RearView
Monitor may differ somewhat from the
actual color of objects.
• Objects on the monitor may not be clear in a dark environment.
• There may be a delay when switching between views.
• If dirt, rain or snow accumulate on the camera, the RearView Monitor may not
display objects clearly. Clean the camera.
• Do not use wax on the camera lens. Wipe off any wax with a clean cloth dampened
with a diluted mild cleaning agent, then
wipe with a dry cloth.

for Intelligent Around View Monitor.
Failure to operate the vehicle in accor-
dance with these system limitations
could result in serious injury or death.
• Do not use the Intelligent Around
View Monitor with the outside mir-
rors in the stored position, and make
sure that the trunk is securely closed
when operating the vehicle using the
Intelligent Around View Monitor.
• The apparent distance between ob-
jects viewed on the Intelligent
Around View Monitor differs from the
actual distance.
• The cameras are installed on the
front grille, the outside mirrors and
above the rear license plate. Do not
put anything such as a license plate
frame on the vehicle that covers or
blocks the view of the cameras.
• When washing the vehicle with high
pressure water, be sure not to spray it
around the cameras. Otherwise, wa-
ter may enter the camera unit caus-
ing water condensation on the lens, a
malfunction, fire or an electric shock. •
Do not strike the cameras. They are
precision instruments. Doing so
could cause a malfunction or cause
damage resulting in a fire or an elec-
tric shock.
There are some areas where the system
will not show objects and the system does
not warn of moving objects. When in the
front or rear view display, an object below
the bumper or on the ground may not be
viewed
O1. When in the bird’s-eye view, a tall
object near the seam
O2of the camera
viewing areas will not appear in the
monitor.
The following are operating limitations and
do not represent a system malfunction:
• There may be a delay when switching between views.
• When the temperature is extremely high or low, the screen may not display objects
clearly.
• When strong light directly shines on the camera, objects may not be displayed
clearly.
• The screen may flicker under fluorescent light.
• The colors of objects on the Intelligent Around View Monitor may differ some-
what from the actual color of objects. • Objects on the Intelligent Around View
Monitor may not be clear and the color of
the object may differ in a dark
environment.
• There may be differences in sharpness between each camera view of the bird's-
eye view.
• Do not use wax on the camera lens. Wipe off any wax with a clean cloth that has
been dampened with a diluted mild
cleaning agent, then wipe with a dry
cloth.
Monitor, climate, audio, phone and voice recognition systems4-25

WARNING
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Closely supervise children when they
are around cars to prevent them
from playing and becoming locked in
the trunk where they could be seri-
ously injured. Keep the car locked,
with the rear seatback and trunk lid
securely latched when not in use, and
prevent children's access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
• Do not breathe exhaust gases; they
contain colorless and odorless car-
bon monoxide. Carbon monoxide is
dangerous. It can cause uncon-
sciousness or death. •
If you suspect that exhaust fumes
are entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
• Do not run the engine in closed
spaces such as a garage.
• Do not park the vehicle with the en-
gine running for any extended length
of time.
• Keep the rear vent windows, lif t-
gates, doors and trunk lids (if so
equipped) closed while driving, oth-
erwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with one of
these open, follow these precau-
tions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial
to high to circulate the air.
• If electrical wiring or other cable con-
nections must pass to a trailer
through the seal on the trunk lid or
the body, follow the manufacturer's
recommendation to prevent carbon
monoxide entry into the vehicle. •
The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involv- ing damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.
WARNING
• The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials
away from the exhaust system
components.
PRECAUTIONS WHEN STARTING AND
DRIVING
5-4Starting and driving

Please observe the following precautions:
WARNING
• Spinning the front wheels on slippery
surfaces may cause the AWD
warning message to display and the
AWD system to automatically switch
from the AWD to the 2WD mode. This
could reduce the traction. Be espe-
cially careful when towing a trailer
(AWD models).
• Drive carefully when off the road and
avoid dangerous areas. Every person
who drives or rides in this vehicle
should be seated with their seat belt
fastened. This will keep you and your
passengers in position when driving
over rough terrain.
• Do not drive across steep slopes. In-
stead drive either straight up or
straight down the slopes. Off-road
vehicles can tip over sideways much
more easily than they can forward or
backward.
• Many hills are too steep for any ve-
hicle. If you drive up them, you may
stall. If you drive down them, you may
not be able to control your speed. If
you drive across them, you may roll
over. •
Do not shif t gears while driving on
downhill grades as this could cause
loss of control of the vehicle.
• Stay alert when driving to the top of a
hill. At the top there could be a drop-
off or other hazard that could cause
an accident.
• If your engine stalls or you cannot
make it to the top of a steep hill,
never attempt to turn around. Your
vehicle could tip or roll over. Always
back straight down in R (Reverse)
gear and apply brakes to control your
speed.
• Heavy braking going down a hill
could cause your brakes to overheat
and fade, resulting in loss of control
and an accident. Apply brakes lightly
and use a low gear to control your
speed.
• Unsecured cargo can be thrown
around when driving over rough ter-
rain. Properly secure all cargo so it
will not be thrown forward and cause
injury to you or your passengers.
• Exceeding the roof rack capacity can
raise the center of gravity excessively
and affect the handling and stability
of the vehicle. •
Secure heavy loads in the cargo area
as far forward and as low as possible.
Do not equip the vehicle with tires
larger than specified in this manual.
This could cause your vehicle to roll
over.
• Do not grip the inside or spokes of
the steering wheel when driving off-
road. The steering wheel could move
suddenly and injure your hands. In-
stead drive with your fingers and
thumbs on the outside of the rim.
• Before operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.
• Always drive with the floor mats in
place as the floor may become hot.
• Lower your speed when encounter-
ing strong crosswinds. With a higher
center of gravity, your NISSAN is more
affected by strong side winds. Slower
speeds ensure better vehicle control.
• Do not drive beyond the perfor-
mance capability of the tires, even
with AWD engaged.
